A method for providing region-specific data content to a plurality of platforms traveling in a plurality of satellite coverage regions as the platforms leave one region and enter another region. Each platform includes a mobile communications system configured for bidirectional communication with a ground segment via satellite link. Within each of the coverage regions, data content selected for the region is multicast to platforms via an associated ground station and satellite. As a platform leaves one of the coverage regions and enters another of the coverage regions, the mobile communications system on the entering platform is configured, via the ground station associated with the coverage region being left, to receive the multicast in the coverage region being entered. This method allows a mobile platform provider automatically to provide its passengers with current and location-specific information, with minimal interruption from satellite handover, as a platform travels from one satellite coverage region to another.
